On December 12, Jeremy Corbyn, head of the Labour Party in the United Kingdom, suffered a great defeat as the conservative Boris Johnson became the new prime minister with a gain of 47 new seats. Labour lost 59 seats. After years of austerity, including cuts to the National Health Service, Corbyn offered a strong manifesto outlining his program for change. We speak with Dr. Leo Panitch, a professor who has studied the Labour Party and left politics since the 1970s. Panitch explains what happened in the UK election and what it potentially means for Senator Sanders' run for president in the United States. He also speaks more broadly about what the left needs to do to build power to the point of having the capability of instituting a progressive platform.
